Circular_text	TITLE: GCN CIRCULAR NUMBER: 25068 SUBJECT: GRB 190714A: MAXI/GSC detection DATE: 19/07/14 14:05:03 GMT FROM: Motoko Serino at RIKEN/MAXI M. Serino (AGU), H. Negoro (Nihon U.), M. Nakajima, W. Maruyama, M. Aoki, K. Kobayashi (Nihon U.), S. Nakahira, T. Mihara, T. Tamagawa, M. Matsuoka (RIKEN), T. Sakamoto, S. Sugita, H. Nishida, A. Yoshida (AGU), Y. Tsuboi, W. Iwakiri, R.

Kurogi, K. Miike (Miyazaki U.), Y. Kawakubo (LSU), T. Kawamuro (NAOJ), K. Yamaoka (Nagoya U.) report on behalf of the MAXI team: The MAXI/GSC nova alert system triggered a bright uncatalogued X-ray transient source at 13:20:27 UT. Assuming that the source flux was constant over the transit, we obtain the source position at (R.A., Dec) = (246.579 deg, 14.917 deg) = (16 26 18, +14 55 01) (J2000) with a statistical 90% C.L. elliptical error region with long and short radii of 0.24 deg and 0.21 deg, respectively. The roll angle of long axis from the north direction is 12.0 deg counterclockwise. There is an additional systematic uncertainty of 0.1 deg (90% containment radius). The X-ray flux averaged over the scan was 230 +- 41 mCrab (4.0-10.0keV, 1 sigma error). Without assumptions on the source constancy,we obtain a rectangular error box for the transient source with the following corners: (R.A., Dec) = (247.817, 15.678) deg = (16 31 16, +15 40 40) (J2000) (R.A., Dec) = (247.520, 15.992) deg = (16 30 04, +15 59 31) (J2000) (R.A., Dec) = (245.586, 14.273) deg = (16 22 20, +14 16 22) (J2000) (R.A., Dec) = (245.884, 13.962) deg = (16 23 32, +13 57 43) (J2000) There was no significant excess flux in the previous transit at UT 11:48 with an upper limit of 20 mCrab for each.

Circular_text	TITLE: GCN CIRCULAR NUMBER: 25069 SUBJECT: GRB 190714A: Tiled Swift observations DATE: 19/07/14 15:43:19 GMT FROM: Phil Evans at U of Leicester P. A. Evans (U. Leicester) reports on behalf of the Swift team: Swift has initiated a series of observations, tiled on the sky, of the MAXI GRB 190714A. Automated analysis of the XRT data will be presented online at http://www.swift.ac.uk/xrt_products/TILED_GRB00081 Any uncatalogued X-ray sources detected in this analysis will be reported on this website and via GCN COUNTERPART notices. The probability of finding serendipitous sources, unrelated to the MAXI event is high: any X-ray source considered to be a probable afterglow candidate will be reported via a GCN Circular after manual consideration. Details of the XRT automated analysis methods are detailed in Evans et al. (2007, A&A, 469, 379; 2009, MNRAS, 397, 1177 and 2014, ApJS, 210, 8). This circular is an official product of the Swift-XRT team.

Kawakubo (LSU) report on behalf of the MAXI team: Swift-XRT performed 7 tiled followup observations for GRB 190714A (Serino et al. GCN 25068; Evans GCN 25069) on July 14th, 2019 (from T0 +7.9 ks to T0 +9.3 ks). We conclude that GRB 190714A is not a GRB, but very likely to be an X-ray flare from the M (or dMe) star 2E 1624.6+1504/UCAC4 525-061488 (for detail, see Negoro et al. ATel #12944).
